Chemical signatures imprinted on tiny stones that form inside the ears of fish show that two of Alaska’s most productive salmon populations, and the fisheries they support, depend on the entire watershed.

On May 4th, the University of Washington held its second annual Aquatic Science Open House. Seattle-area families, students, and teachers were invited to explore the institution’s marine and freshwater science programs and interact with researchers. The event was organized by the Students Explore Aquatic Sciences (SEAS) outreach group based in the School of Aquatic and Fishery Sciences (SAFS) and the Academic and Recreational Graduate Oceanographers (ARGO) outreach group based in the School of Oceanography.

Just over one-third of the world’s 246 longest rivers remain free-flowing, according to a new study published May 8 in Nature. Dams and reservoirs are drastically reducing the diverse benefits that healthy rivers provide to people and nature across the globe.

We are proud and thrilled to share the news that School of Aquatic and Fishery Science faculty member Dr. Jacqueline Padilla-Gamiño has been selected by the Latino Center for Health at UW to be recognized at the Latinx Faculty Recognition Event. This annual event honors the scholarly achievements of Latina and Latino faculty across the tri-campuses of the University of Washington for the academic year 2018-2019.

In rural communities across the tropics, a parasitic disease called schistosomiasis that is carried by freshwater snails currently infects more than 220 million people, rivaling malaria in its prevalence. Capable of residing in an infected human for more than 30 years, the Schistosoma parasite can cause debilitating and often-fatal health complications, including liver failure, bladder cancer, and an increased risk of AIDS. An estimated 280,000 people in Africa alone die each year from the disease. Despite 50 years of medical intervention and the availability of a relatively inexpensive and effective drug, the disease has stubbornly resisted eradication efforts, largely due to the ease with which the parasite reinfects its human hosts.

The Ocean Modeling Forum (OMF) is a University of Washington program run through the School of Aquatic and Fishery Sciences that aims to bring together interdisciplinary scientists, modeling experts, decision makers, and other people invested in ocean resources. The OMF helps managers frame questions, understand the strengths and limitations of different models, and learn how to incorporate models in their work.

Citizen science, where the nonexpert public joins in freely to produce useful science, has grown to more than 2100 projects on the SciStarter website alone. These projects range from online identification of astronomical objects, to gaming-like projects predicting how proteins will fold (Foldit), to seasonal bird counts. One long-running project is COASST (Coastal Observation and Seabird Survey Team) where members of the public conduct monthly surveys of beach areas from California to Alaska looking for bird carcasses.

This winter, Greg Jensen is releasing his follow-up book, Beneath Pacific Tides: Subtidal Invertebrates of the West Coast. Like the charismatic crustaceans featured in his debut publication, the colorful and bizarre invertebrates found along the Pacific Coast are explored in this new user-friendly guide, featuring Jensen’s underwater photography.
